													    | Abstract  Objective To clarify the characteristics of motor development and the incidence of motor developmental delay in children with simple congenital heart disease (CHD). Methods A total of 357 consecutive simple CHD children aged 0 -6 years were recruited. The second edition of the Peabody motor development scale (PMDS -2)was used to assess the motor development level of all children. Scores of fine motor quotient(FMQ), gross motor quotient(GMQ) , and totalmotor quotient (TMQ)were calculated. GMQ score < 90 was defined as gross motor developmental delay, FMQ score < 90 as fine motor developmental delay, and TMQ < 90 as total motor developmental delay. Results There were significantdifferences in scores of FMQ, GMQ, and TMQ among different types of CHD (P<0.05). GMQ in girls with CHD wassignificantly lower than that in boys with CHD (P=0.003). The prevalence of gross motor developmental delay in children with CHD was 37.5%, the prevalence of fine motor developmental delay was 11.8%, and the prevalence of total motor developmental delay was 29.1%. Conclusion Children with simple CHD aged 0 -6 years have a higher prevalence of motor developmental delay. Simple CHD children with different gender and CHD types have different levels of motor function development. |
